IN V EN TOR. C. Rezanso ff United States Patent 3,351,269 ENVELOPE Cecil Rezansoff, Benito, Manitoba, Canada Filed Nov. 8, 1965, Ser. No. 506,757 1 Claim. (Cl. 22975) ABSTRACT OF THE DISCLOSURE An envelope including a front panel bounded by four flaps which are folded over to form a rear wall, each of the flaps being of generally triangular configuration, and two of the flaps upon opposite sides when folded over having one edge which is in edge abutment with each other, while the other two flaps provide securement means for retaining the four flaps in a rear wall position of the envelope.

This invention relates to paper receptacles and folded containers, and more particularly to an envelope.

It is therefore the main purpose of this invention to provide an envelope which is designed in such a manner as to prevent unauthorized removal of contents therefrom.

Another object of this invention is to provide an envelope wherein front flap is considerably narrow thereby providing more effective sealing of the envelope.

Another object of this invention is to provide an envelope which is sturdy and can be used as a dispatch case for documents.

Still another object of this invention is to provide an envelope which is easy to manufacture and provides maximum utility to its user.

Other objects and advantages of this invention will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is not shown. However, it is to be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claims.

In the drawing:

FIGURE 1 is a rear view of this invention shown in elevation;

FIGURE 2 is a plan view showing the development thereof;

FIGURE .3 is a front elevational view of FIGURE 1;

FIGURE 4 is a rear elevational view showing a modified form of this invention.

According to this invention, envelope is provided with edges 11 and 12 which converge one toward another. On the other side of envelope 10 edges 13 and 14 are provided which are substantially similar to edges 11 and 12. Top portion of the blank includes an upwardly inclined edge 15, edge 16 is also an inclined edge which is located on the opposite end of edge 15. The inclined angle of edge is of different angular direction and that one of edge 16. Edges 31 and 32 conect edge 15 to edges 13 and 11. Edges 33 and 34 connect edge 16 to edges 14 and 12. At each edge of the blank of the envelope 10 straight line folding marks are provided as 3,351,269 Patented Nov. 7, 1967 indicated by 21, 22, 23 and 24. Therefore, edges 11, 12 and folding line 23 form a flat 17 of substantially triangular configuration. Edges 13, 14 and folding line 24 form flat 18 which is on the opposite side of main body 25. Edges 15, 31, 32 and folding line 21 form a flap 19. Flat 20 is formed by folding line 22 and edges 16, 33 and 34. It can be seen from FIGURE 1 that when folded edges 11 and 13 are adjacent one to another and flaps 19 and 20 overlap upper and lower portions of flaps 17 and 18. Flap 20 is terminately secured to the bottom portions of flaps 17 and 18, which flaps are secured one to another by means of gumrning since adjacent edge 13 overlaps edge 11. Gumrning (not shown) is also provided for flap 19 for securing said flap to the upper portions of flats 17 and 18, when needed.

Looking now at FIGURE 4 of the drawing, one will see that a different type of blank is provided having a normally open flap 29 and the remaining flaps 28, 27 and 30 being secured one to another by gumming means. Despite the fact that the envelope shown in FIGURE 4 has somewhat dilferent configuration from the main embodiment, the inventive scope is same as that one shown in FIG- URES 1, 2 and 3 since it produces an envelope with a small front flap.

What I now claim is:

An envelope comprising a blank which includes a body portion, longitudinally positioned flaps extending from said body portion, laterally extending flaps extending from said body portion, said flaps adapted to fold towards said body portion, two of said flaps upon opposite sides partially overlapping one another, securing means for securing said flaps to one another and one of said laterally positioned flaps being left open to provide access into said envelope, said longitudinally positioned flaps being substantially triangular in configuration, and said laterally positioned flaps having their outer edges assume inclined angles in an opposite direction one from another, said securing means including gumming substance, one open flap being provided with gumrnin-g substance for sealing said envelope, and one side of one said longitudinally positioned flaps being in edge abutment with a corresponding edge of a side flap opposite the said lon tudinally positioned flap to form an open slot between said longitudinally positioned flaps, said open slot being bounded at its ends by said laterally positioned flaps when said envelope is closed.
